Description

Lenkrad mit mindestens einem Verkleidungsteil Steering wheel with at least one trim part
Beschreibungdescription
Die Erfindung betrifft ein Lenkrad mit mindestens einem Verkleidungsteil nach dem Oberbegriff des Anspruchs 1.The invention relates to a steering wheel with at least one trim part according to the preamble of claim 1.
Lenkräder bestehen im allgemeinen aus einem Lenkradskelett, das mit einer Umhüllung aus Kunststoff, z.B. Polyurethan, versehen ist. Zusätzlich werden auf das Lenkrad häufig Verkleidungsteile aus formstabilem Werkstoff aufgeklebt. Diese Verkleidungsteile haben eine Schmuckfunktion, indem sie z.B. eine sichtbare Holzoberfläche aufweisen.Steering wheels generally consist of a steering wheel skeleton covered with a plastic covering, e.g. Polyurethane is provided. In addition, trim parts made of dimensionally stable material are often glued to the steering wheel. These trim parts have a decorative function, e.g. by have a visible wood surface.
Der Nachteil dieser Verkleidungsteile besteht darin, daß die Herstellung der Klebeverbindung zeitaufwendig ist, da das Lenkrad solange in einer Klebevorrichtung verbleiben muß, bis der Kleber ausgehärtet ist. Da das Lenkrad Schwingungen ausgesetzt ist, ist nicht ganz auszuschließen, daß sich die Klebeverbindung löst.The disadvantage of these trim parts is that the production of the adhesive connection is time-consuming since the steering wheel must remain in an adhesive device until the adhesive has hardened. Since the steering wheel is exposed to vibrations, it cannot be completely ruled out that the adhesive connection will come loose.
Der Erfindung liegt deshalb die Aufgabe zugrunde, eine schnelle und sichere Verbindung eines Verkleidungsteiles mit dem Lenkrad zu erzielen.The invention is therefore based on the object of achieving a quick and secure connection of a trim part to the steering wheel.
Erfindugnsgemäß wird daß gemäß den Merkmalen des Anspruchs 1 erreicht.According to the invention that is achieved according to the features of claim 1.
Bei einem Lenkrad mit mindestens einem Verkleidungsteil, ist erfindungsgemäß zwischen dem Lenkrad und dem Verkleidungsteil mindestens ein mechanisches Verbindungselement vorgesehen. Vorzugsweise ist ein clipsartiges Verbindungselement vorgesehen.In the case of a steering wheel with at least one trim part, according to the invention there is at least one mechanical connecting element between the steering wheel and the trim part intended. A clip-like connecting element is preferably provided.
Diese Verbindungsart weist den Vorteil auf, daß das Verkleidungsteil durch einen kurzzeitigen Druck mit dem Lenkrad verbunden werden kann. Zusätzlich kann auch in diesem Fall zwischen dem Verkleidungsteil und dem Lenkrad eine Klebestelle vorgesehen sein. Die mechanischen Verbindungselemente gewährleisten den erforderlichen Andruck des Verkleidungsteils, so daß eine Klebevorrichtung nicht mehr erforderlich ist.This type of connection has the advantage that the trim part can be connected to the steering wheel by brief pressure. In addition, an adhesive point can also be provided in this case between the trim part and the steering wheel. The mechanical connecting elements ensure the required pressure of the trim part, so that an adhesive device is no longer required.
In einer bevorzugten Ausführungsform ist vorgesehen, daß Clips an der Einlage des Lenkradkranzes befestigt sind und daß den Clips am Verkleidungsteil Aussparungen zugeordnet sind, in die die Clips eindrückbar sind. Die Clips sind zweckmäßig so ausgebildet, daß sie die Lenkradkranzeinlage teilweise umgreifen und daß sie in dem Bereich, der den Aussparungen am Verkleidungsteil zugeordnet ist, Abschnitte aufweisen, die zumindest teilweise nach außen aufgebogen sind. Diese aufgebogenen Abschnitte erhöhen den sicheren Halt der Clips in den Aussparungen des Verkleidungsteils.In a preferred embodiment it is provided that clips are attached to the insert of the steering wheel rim and that the clips on the trim part are assigned recesses into which the clips can be pressed. The clips are expediently designed in such a way that they partially encompass the steering wheel rim insert and that in the area which is assigned to the cutouts on the trim part, they have sections which are at least partially bent outwards. These bent sections increase the secure hold of the clips in the recesses of the trim part.
Eine weitere Ausgestaltung sieht vor, daß die aufgebogenen Abschnitte symmetrisch zueinander verlaufende Spitzen aufweisen.A further embodiment provides that the bent-up sections have symmetrical tips.
Die mechanischen Verbindungselemente erstrecken sich zweckmäßig in den unteren Teil der Lenkradumhüllung hinein und/oder diese umgreift nach oben die Clips zumindest teilweise . Hierzu werden die Verbindungelemente vor dem Aufbringen der Umhüllung auf das Lenkradskelett vorzugsweise auf die Einlage aufgesteckt, so daß sie beim Aufbringen der Umhüllung fest mit dieser verbunden werden. Es ist weiterhin zweckmäßig, daß die Clips im unteren Teil nach außen abgebogene Enden aufweisen. Dadurch ist eine noch bessere Haftung in der Umhüllung erreichbar.The mechanical connecting elements expediently extend into the lower part of the steering wheel casing and / or at least partially surrounds the clips upwards. For this purpose, the connecting elements are preferably plugged onto the insert before the covering is applied to the steering wheel skeleton, so that they are firmly connected to the covering when the covering is applied. It is furthermore expedient that the clips have ends bent outwards in the lower part. This enables even better adhesion in the wrapper to be achieved.
Bei einer weiteren Ausführungsform ist das clipsartige Verbindungsteil neben der Lenkradkranzeinlage angeordnet, und das Verkleidungsteil weist mindestens eine über das clipsartige Verbindungsteil greifende Spange auf. Dadurch, daß das clipsartige Verbindungsteil neben dem Skelettring angeordnet ist, kann in einfacher Weise auch ein Verkleidungsteil am Lenkrad befestigt werden, daß nur einseitig am Lenkrad verlaufen soll.In a further embodiment, the clip-like connecting part is arranged next to the steering wheel rim insert, and the cladding part has at least one clasp that extends over the clip-like connecting part. Because the clip-like connecting part is arranged next to the skeleton ring, a trim part can also be attached to the steering wheel in a simple manner that should only run on one side on the steering wheel.
In einer bevorzugten Ausgestaltung dieser Ausführungsform ist das clipsartige Verbindungsteil auf einem Zentrierblech angeordnet, das in der Lenkradumhüllung und/oder am Skelettring befestigt ist. Dabei weist das clipsartige Verbindungsteil einerseits gegenüber dem Zentrierblech wirksame aufgebogene Abschnitte und andererseits weitere gegenüber der Spange wirksame aufgebogene Abschnitte auf .In a preferred embodiment of this embodiment, the clip-like connecting part is arranged on a centering plate which is fastened in the steering wheel casing and / or on the skeleton ring. Here, the clip-like connecting part has, on the one hand, bent-up sections which are effective with respect to the centering plate and, on the other hand, further bent-up sections which are effective with respect to the clasp.
Die Spange ist im Bereich des clipsartigen Verbindungsteils verformbar und/oder weist Öffnungen für den Eingriff der aufgebogenen Abschnitte auf. Das Zentrieblech weist ebenfalls Öffnungen für den Eingriff der aufgebogenen Abschnitte auf.The clasp can be deformed in the region of the clip-like connecting part and / or has openings for the engagement of the bent-up sections. The center plate also has openings for the engagement of the bent sections.
In einer Ausführungsform besteht die Spange aus Holz und weist für den Eingriff des clipsartigen Verbindungsteils einen Einsatz aus Kunststoff auf.In one embodiment, the clasp is made of wood and has an insert made of plastic for the engagement of the clip-like connecting part.
Die Erfindung soll in Ausführungsbeispielen anhand von Zeichnungen erläutert werden. Es zeigen:The invention will be explained in exemplary embodiments with reference to drawings. Show it:

Ein Lenkrad 1, weist als wesentliche Bestandteile ein Skelett mit Speichen 2 und einer Lenkkranzeinlage 3 auf, die von einer Hülle 4, insbesondere aus PUR-Schaum umgeben sind. Auf seiner Oberseite ist das Lenkrad mit Verkleidungsteilen 5, 6 versehen. Diese erstrecken sich nicht über die gesamte Oberseite des Lenkrades sondern sind als Segmente angeordnet, wobei das Verkleidungsteil 5 länger ist als das Verkleidungsteil 6. Wie aus den Figuren 3 und 4 ersichtlich ist, bestehen die Verkleidungsteile aus einem Träger 7 aus Aluminium-Druckguß, auf den eine Holzbeschichtung aufgebracht ist. Diese besteht aus einem Unterfurnier 8 und einem Deckfurnier 9, das durch eine Polyesterschicht 10 versiegelt ist.A steering wheel 1 has as essential components a skeleton with spokes 2 and a steering ring insert 3, which are surrounded by a cover 4, in particular made of PUR foam. The steering wheel is provided with trim parts 5, 6 on its upper side. These do not extend over the entire top of the steering wheel but are arranged as segments, the trim part 5 being longer than the trim part 6. As can be seen from FIGS. 3 and 4, the trim parts consist of a support 7 made of die-cast aluminum which has a wood coating applied. This consists of a lower veneer 8 and a cover veneer 9, which is sealed by a polyester layer 10.
Auf der Lenkkranzeinlage 3 sind mehrere Clips 11 angeordnet. Die Anzahl der Clips ist von der Länge des Verklei- dungsteiles abhängig. So sind dem Verkleidungsteil 5 vier Clips und dem Verkleidungsteil 6 drei Clips zugeordnet (nicht dargestellt) . Die Figuren 3 bis 5 zeigen, daß die Clips im Bereich der Lenkkranzeinlage 3 einen an deren kreisförmigen Querschnitt angepaßten Querschnitt aufweisen, so daß sie die Lenkkranzeinlage teilweise umgreifen und damit auf dieser verankert sind. Beim Aufsetzen auf die Lenkkranzeinlage werden die Clips elastisch aufgebogen und legen sich dann eng an die Lenkkranzeinlage an. Die Clips weisen im unteren Teil nach außen abgebogene Enden 12, 13 auf. Diese ragen in die Hülle 4 hinein und gewährleisten zusätzlich den festen Sitz der Clips. Zusätzlich umgreift die Hülle 4 mit einem Abschnitt 4a die Clips 11.Several clips 11 are arranged on the steering wheel insert 3. The number of clips depends on the length of the part of the manure. For example, four clips are assigned to the covering part 5 and three clips are assigned to the covering part 6 (not shown). FIGS. 3 to 5 show that the clips in the area of the steering wheel insert 3 have a cross section which is adapted to their circular cross section, so that they partially grip around the steering wheel insert and are thus anchored on it. When placed on the steering wheel insert, the clips are bent open elastically and then lie closely against the steering wheel insert. The clips have ends 12, 13 bent outwards in the lower part. These protrude into the casing 4 and additionally ensure the clips are securely seated. In addition, the cover 4 surrounds the clips 11 with a section 4a.
Oberhalb der Lenkkranzeinlage 3 ist jeder Clip in seinem Querschnitt an den Querschnitt je einer Aussparung 14 im Träger 7 angepaßt, in die er eingedrückt wird. Insbesondere aus den Figuren 5 und 6 ist erkennbar, daß die Clips in diesem Bereich Abschnitte 15, 16 aufweisen, die zumindest teilweise nach außen aufgebogen sind. Die aufgebogenen Abschnitte weisen symmetrisch zueinander verlaufende Spitzen 17, 18 auf. Die so geformten Abschnitte gewährleisten zusätzlich eine feste Verbindung zwischen dem Träger 7 und den Clips 11.Above the steering ring insert 3, each clip is adapted in its cross section to the cross section of a recess 14 in the carrier 7, into which it is pressed. It can be seen in particular from FIGS. 5 and 6 that the clips in this area have sections 15, 16 which are at least partially bent outwards. The bent sections have points 17, 18 which run symmetrically to one another. The sections shaped in this way additionally ensure a firm connection between the carrier 7 and the clips 11.
Zusätzlich zu der mechanischen Befestigung werden der Träger 7 und die Hülle 4 miteinander verklebt. Dabei ist ein Raum 19 mit Kleber ausgefüllt. Aus der Fig. 3 ist ersichtlich, daß die Hülle 4 schmaler ist als das Verkleidungsteil 5, so daß sie noch mit einer weiteren Schicht umhüllt werden kann, z.B. mit einer umlaufenden Lederauflage (nicht dargestellt) , so daß die Hülle 4 dann die gleiche Breite wie das Verkleidungsteil 5 aufweist.In addition to the mechanical fastening, the carrier 7 and the sleeve 4 are glued together. A space 19 is filled with adhesive. From Fig. 3 it can be seen that the casing 4 is narrower than the covering part 5, so that it can be covered with a further layer, e.g. with a circumferential leather pad (not shown), so that the sleeve 4 then has the same width as the trim part 5.
In der Fig. 7 ist ein Ausführungsbeispiel mit einem einseitig angeordneten Verkleidungsteil 5 dargestellt. Aus der vergrößerten Darstellung des Lenkradkranzes in der Fig. 8 ist ersichtlich, daß die Hülle 4 mit Weichschaum 20 überdeckt ist, der mit Leder 21 verkleidet ist. In der Darstellung des Lenkradkranzes ist links neben der Lenkradkranzeinlage 3 ein freistehendes Zentrierblech 22 angeordnet, das in der Hülle 4 befestigt ist. Dieses Zentrierblech dient der Befestigung des Verkleidungsteils 5. Hierzu sind auf dem Zentrierblech 22 Clips 23 vorgesehen, die aufgebogene Abschnitte 24, 25 aufweisen, mittels derer sie auf dem Zentrieblech 22 gehalten werden.7 shows an embodiment with a cladding part 5 arranged on one side. From the 8 shows that the cover 4 is covered with soft foam 20, which is covered with leather 21. In the illustration of the steering wheel rim, a free-standing centering plate 22 is arranged to the left of the steering wheel rim insert 3 and is fastened in the casing 4. This centering plate is used to fasten the trim part 5. For this purpose, clips 23 are provided on the centering plate 22, which have bent sections 24, 25, by means of which they are held on the center plate 22.
Das Verkleidungsteil 5 besteht aus einer Spange 26, die mit einer Kunststoffeinlage 27 versehen ist. Dieser sind aufgebogene Abschnitte 15, 16 der Clipse 23 zugeordnet, die sich beim Aufsetzen der Spange 26 in diese eindrücken oder in Öffnungen (nicht dargestellt) der Kunststoffeinlage 27 eingreifen, wodurch das Verkleidungsteil 5 am Lenkrad befestigt wird. Das Verkleidungsteil soll in der Regel eine Holzstruktur aufweisen. Deshalb ist die Spange 26 mit einem Unterfurnier 28 und einem Deckfurnier 29 verkleidet, das durch eine nicht dargestellte Polyesterschicht versiegelt ist. Es ist aber auch möglich, die Spange aus einem Holz herzustellen, dessen Oberfläche sichtbar sein soll und die Oberfläche so zu behandeln, daß kein Furnier erforderlich ist. The trim part 5 consists of a clasp 26 which is provided with a plastic insert 27. This is associated with bent sections 15, 16 of the clips 23, which press into the clip 26 when the clip is placed or engage in openings (not shown) in the plastic insert 27, as a result of which the trim part 5 is fastened to the steering wheel. The trim part should usually have a wooden structure. Therefore, the clasp 26 is covered with a lower veneer 28 and a cover veneer 29, which is sealed by a polyester layer, not shown. But it is also possible to make the clasp from a wood whose surface should be visible and to treat the surface so that no veneer is required.
